The diffusive bodies are designed to house Radiello cartridge adsorbents during sampling. The diffusive bodies are threaded at one end for easy attachment to the Radiello triangular support plate. Unlike most of the cartridge adsorbents, the diffusive bodies are reusable and can be cleaned with a mild detergent between use. The diffusive bodies will collect dust (especially during outdoor sampling) and replacement is recommended after 4-5 uses. Dimensions are 60 mm height x 16 mm diameter. There are four different diffusive bodies available. Each of which are application specific in design.
